Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Drydeshaling: Noncoal or shalycoal is removed without using any liquid media.
Dry beneficiation technology of coal with an air densemedium fluidized bed commenced application lately in China.
